Detecting resize events

[tinman]

Hi,

What is the best way to handle resize events? I have a CanvasGadget that displays a map that is locked to all sides of the window. If the window is resized then I want to redraw the map to fill the CanvasGadget. Currently I have to have extra code in my event loop to handle this resize in addition to the ResizeGadgetsWindow_0 procedure that is generated, and it does not really fit with the way of defining event procedures.

For example, I have this:

Code: Select all

  Repeat
    ev = WaitWindowEvent()
    
    Select EventWindow()
      Case MainWindow
        If MainWindow_Events(ev) = #False
          quit = #True
        ElseIf ev = #PB_Event_SizeWindow
          DrawMap(@map_area)
        EndIf
        
    EndSelect
    
  Until quit

Since there does not seem to be a way to catch it from an event procedure, which would be more consistent.

Thanks.

maybe you looking for this ?

Code: Select all

Procedure myResizeEvent()
  
  DrawMap(@map_area)
  ; do whatever todo at window resize
  
EndProcedure

BindEvent(#PB_Event_SizeWindow, @myResizeEvent(), MainWindow)

Hi Bisonte,

Thank you. Yes, I had missed that as a new feature in 5.20. However, the problem with using BindEvent is that it gets called before the FormDesigner resize procedure so I would not know what the new size was as the CanvasGadget would not have been resized by the time the callback is active.

Hi Justin,

Thanks I've chipped in to add to your request. Hopefully it might be added, but I'll just have to live with the code I have for now.

Cheers.
